Checkout this site. $89 UQ, $89 TQ. Both rated to 40-45 degrees. Each weigh 19 ounces or less with stuff sack. Dave(owner) is an awesome guy with very innovative ultralite ideas(met him at the Hoosier Hang and took a look at his stuff, it is very nice). Hopefully he will be on here to add a few words or corrections if I got anything wrong.
Mods: I offered to post this for Dave. So if there are any issues please let me know. Thanks.
